Circulant symmetric method
WebCall that matrix A and notice that it is a permutation of a circulant matrix, A = CP Where P is a permutation matrix with ones on the anti-diagonal, and zeros in all other positions. Then det [A] = det [CP] = det [C] det [P] The determinant of the permutation part can be shown to depend on the size n. WebA recursive method has been found to construct V4, by circulant 2n X 2ii matrices which are derived by circulant n X n submatrices of a given V27.. (See Theorem 1, below.) Likewise, let W4, be an H47.-matrix of Williamson type with odd n; W8' can be constructed by using 2n X 2n symmetric circulant matrices which are derived

WebAn iteration method is constructed to solve the linear matrix equation AXB=C over symmetric X. By this iteration method, the solvability of the equation AXB=C over symmetric X can be determined automatically, when the equation AXB=C is consistent over symmetric X, its solution can be obtained within finite iteration steps, and its least-norm … WebMultiplying by a circulant matrix is equivalent to a very famous operation called acircular convolution. Convolution operations, and hence circulant matrices, show up in lots of …

This analysis is performed for input frequencies located around any harmonic frequency of the local-oscillator (LO). From this, circuits and methods are introduced which allow control of the receiver’s harmonic input impedance through use of resistive-

Unlike the traditional fixed-rule-based univariate time series visibility graph methods, a symmetric adaptive visibility graph method is proposed using orthogonal signals, a method applicable to in-phase and …
WebCirculant networks are a very important and widely studied class of graphs due to their interesting and diverse applications in networking, facility location problems, and their symmetric properties. The structure of the graph ensures that it is symmetric about any line that cuts the graph into two equal parts. Due to this symmetric behavior, the …
